    SD card

    One of the reasons an Android phone won’t turn on is to use a larger SD card than the manufacturer claims. The craving for experimentation is in the blood of users. If the specification says that only 32 GB can be used, they will definitely try 64. With a high degree of probability, the device will recognize the card. It will work normally until the recorded amount of information exceeds the one declared for support.

    If, after a software failure, the phone stops turning on or does not boot, it is enough to remove the problem memory card from it. A forced reboot will bring the smartphone to a working state.

    What to do if your phone won’t turn on or respond to charging

    Modern smartphones devices are complex and delicate enough. One “fine” morning, you may find that the gadget, which was put on charge, refuses to work. Today we will figure out what to do if the phone does not turn on or boot, as well as how you can fix this problem at home.

    There are not so many answers to the question why the phone does not turn on, what may be the reason for its rapid discharge and what to do in such a situation. Let’s consider the most common options and solutions.

    System errors and failed updates

    System errors, or a resource-intensive application that is not completely unloaded from RAM, can lead to the fact that the battery starts to drain rapidly, as a result of which the phone turns off and does not start again. A malicious program can behave in a similar way. The virus, if its task is not to extortion, runs in the background. At the same time, he tries to use all available resources as quickly as possible. If your Android phone runs out of power faster than usual while in idle state, you should check it for infection and perform a forced reboot. Further actions depend on the results of the anti-virus scan.

    If the smartphone is clean and charged normally, there is no cause for concern. Otherwise, if the device does not start or the phone runs out of power again quickly, a full reset and reconfiguration will be required.

    An unsuccessful software update can lead to the phone not responding to user actions or simply turning off. Usually, this behavior is easily “cured” by a reboot.

    In case of a failure when flashing to a new version of the OS, the situation is a little more complicated. When the phone starts up, but the download does not go beyond the splash screen, the recovery mode can save the situation. What to do and how to enable Recovery Mode for a specific phone is best found on the manufacturer’s website or in the documentation for the device. When this is not possible, try generic methods. The vast majority of smartphones based on Android support it by pressing the power and volume keys. It will be an Up or Down button, depending on the manufacturer of the device. You can try both options sequentially.

    Adapter defective or missing contact

    The most common reason why a phone won’t boot or run out of power quickly is a malfunctioning charger. To verify this, you need to connect the gadget to another power supply. If it starts charging, then you have found the cause and the problem was in the charger. You can do the opposite, connect a known working phone to a suspicious power supply. Thus, you are guaranteed to be convinced of its malfunction.

    If the smartphone does not charge from a working power supply, check the connector of the contacts. A clot of dust or pet hair can get into it. Gently use a wooden or plastic toothpick to clean the connection socket on the phone and try again.

    If your phone has a removable battery, check the contact fit and condition. There is a possibility that they were oxidized by moisture or bent when the battery was inserted after being dropped.

    Another opportunity to “revive” the battery or make sure it is working properly is to use a universal charger. In common parlance, it is called “frog” and is capable of charging any removable battery from a household electrical network.

    Hidden defects

    Some users believe that physical damage is when the phone fell on a hard surface and shattered to smithereens. Prior to this moment, he also fell twice, but only “slightly” scratched and wrinkled. Meanwhile, it is impossible to exclude the appearance of hidden defects from the impact on the body of the gadget. Damage to the internal contacts will result in the Android phone not turning on or charging, and sometimes working and suddenly shutting down. So if your phone has fallen, it is impossible to fix the motherboard malfunction on your own and you will have to contact a specialist for a complete diagnosis and possible replacement of components.

    If the phone does not turn on even after you have gone through all the probable reasons, you should contact the service center. Without showing excessive initiative in attempts to revive it, you will save yourself time and nerves for specialists.
